GCSE Geography: Resource Management - Energy Guide

Global energy demand

Global energy demand is rising, driven by population growth and economic development, particularly in newly emerging economies where rising incomes increase energy use.

Energy supply

Energy comes from non-renewable sources (fossil fuels like coal, oil and gas, and nuclear) and renewable sources (such as wind, solar, hydroelectric and biomass), each with different costs, reliability and environmental impacts.

Fossil fuel issues

Fossil fuels are a finite resource, and burning them releases greenhouse gases that contribute to climate change, creating pressure to shift towards alternative sources.

Sustainable energy strategies

Strategies for a more sustainable energy future include increasing renewable energy use, improving energy efficiency, and international agreements to reduce reliance on fossil fuels.

Common mistakes

• Assuming all renewable energy sources are equally reliable — some, like solar and wind, depend on weather conditions.
• Forgetting nuclear power is non-renewable but produces very low carbon emissions.
• Describing a strategy without weighing its advantages and disadvantages.
